Used and sad

He was so nice to me at first. I was in love with him. He was so beautiful to me. Now I am stuck. I am a 22 year old petite white man. My boyfriend is a 220 pound black body builder. I have been living with him for a year. He is wealthy and I have no career. I was working as a receptionist at a gym making minimum wage and living with my parents when we met. Now I am so unhappy. I want to leave him but I would have to move back in with my parents. I was so in love with him. Now he has parties and lets his friends f*** me. I liked it at first. Now he is very disrespectful to me and hits me sometimes in front of his friends.
